Application filed November 6, 1920. Serial No. 422,198.

To all whom it may concern.

Be it known that I, Gnoncn W. ARNOLD, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Ore-Separators, of which the following is a specification.

The present invention is directed to improvements in ore separators, and has for its primary object to provide an apparatus of this character so constructed that the ore will be effectively separated by agitation.

A further object of theinvention is to provide an apparatus of this nature so constructed and arranged as to subject the pulp to agitation in such a manner as to assure.

practically maximum separation of the ore.

A still further object of the invention is to provide a separator of this character which is extremely simple in construction, durable, eliicient in operation, and one which can be manufactured at a very small cost.

lVith these and other objects in view, this invention resides in the novel features of con struction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which Figure l is a perspective view of the devlce.

tional view.

Fig. 3 is a side elevation, partly in section.

Fig. 4: is a sectional view on line H of Fi Fig. 5 is a detail view of the apron adjustment.

Fig. 6 is an enlarged detail sectional view to more clearly illustrate the manner in which the deck and rilfles are connected.

Referring to the drawings, 1 designates the deck, preferably formed from sheet metal, said deckhaving formed adjacent its rear edge a longitudinal pocket'2, the purpose of which will appear later. A sheet 3 of linoleum is placed upon the upper surface of the deck 1, and resting on the sheet are the horizontal webs of the angle iron riiiles 4: and 5, the former being somewhat greater in hei 'ht than the latter.

uitably secured to the ends'of the deck, and abutting the ends of the riflles 1 and 5, are end plates 6, and adjustably supported by said plates is an inclined apron 7, the

lower end of which terminates in a vertical depending flange 8, which is disposed be- Fig. 2 is. a fragmentary transverse SEC".

tweenthe riflles 1 and 5, as clearly shownin Fig. 2 of the drawings, the purpose of which will later appear.

Associated with the front and rear edges of the deck 1 are tailings and concentrates conducting aprons 9 and 10, respectively.

A pair of channel beams 11 are employed, and have their bases resting on any suitable support. Having their lower ends fixed to the beams are resilient arms 12, four of which are preferably employed, said arms having their upper ends terminating in horizontal heads 13.

It will be observed that the clamping bolts 14- not only serve to secure the resilient arms 12 to the deck 1, but alsoserve to secure the aprons 9 and 10, riifles 4.- and 5, and the sheet 3 in proper relation with respect to said deck.

Mounted on th beanisll are brackets 15, and suitably journaled therein is a drive shaft 16, upon which are mounted adjustable eccentrics 17, preferably two being employed.

Depending from the ends of the deck 1 are cars 18, and pivotally therewith are the forward ends of the pitmen 19, the rear ends of which being provided with straps 20 for engagement with the eccentrics 17 in the usual manner.

is essential that the apron 7 be adjustable horizontally and vertically, and in order Patented Nov.15,1921.

to accomplish this the sides 6 are formed or vertically so that the flange 8 may be moved toward or away from the riflles 4 and 5, and vertically with respect to the deck 1..

Carried by one end of the shaft 16 are belt pulleys 23 and 24, the former being fixed thereto while the latter is loose thereon, whereby a belt may be shifted to the loose pulley when it is desired to stop vibrating the deck.

The resilient arms 12 are normally in the positions as shown in full lines in-Fig. 3, and upon rotary motion being imparted to the shaft 16 the pitmen 19 will be reciprocated, whereby the deck will be moved forwardly, as will the apron 7, the arms will flex to the position as shown in dotted lines. It will be obvious that during the vibration of the deck the return movement thereof will be much quicker than the forward movement due to the flexibility of the arms 12 and construction of the eccentric 17, which action being essential in devices of this character.

It will also be observed that the deck will have in addition to the straight vibratory movement, a rocking movement. I

Since the eccentrics 17 are adjustable the throw of the pitmen may be readily regu lated as desired, thus providing means for regulating the vibratory movement ofthe deck.

In operation, the shaft 16 is rotated atthe desired speed to impart to the deck the proper vibration, whereupon the pulp and wash water is directed from the usual launder upon the apron 7. It will be of course understood that the apron 7 has been adjusted'so that the lower edge of the flange 8 will be spaced the proper distance from the deck 1 to suit the class of ore to be separated, whether coarse or fine. F or instance, if the ore is fine the flange 8 will be comparatively r the flange-8 and riflle 41 will be causedto' close to the deck. The apron beinog'rather widerwill permit the mineral to settle thereon before leaving the lower edge,'after which itwill drop onto the deck, while the water will be projected toward the riflie 4.

The water collected on the plane between formwaves due to the vibration of the deck 1, whereupon the tailings will pass over the rifile 4 onto the apron 9, where it can be dis- "posed of as desired. The mineral passing under thefiange 8 willentertheplane be-. tween the flange 8 and riflie 5, the same wave movement being present in this plane. This wave movement will cause the concentrates to pass over the riftle 5, and onto the apron 10 where it may be disposed of suitably.

Any free gold entering the plane between the flange 8 and. rii'lle 5 will collect in the pocket 2, and may be easily removed there- '40.

fromwvhen desired; I V

. By placingthe flange 8 between the riiiles l and .5 front and rear planes are provided,

and it will be readily seen thatthe vibration to which the deck is subjected will cause the minerals, which collect onthelinoleum sheet 3 to "pass from the front plane to the rear plane. VVhilematerial other-than linoleum may be used for covering the'deck, it has been found from actual experience that lineoleum has minerals.

sensitive holding action on WVhat is claimed is:

l .1. Inaseparator of the class described, the combination with a deck'having front and "rear riflies," an inclineda-pronhaving a vertical depending flangepositioned between the rifiles, meanswhereby the apron and thus the flange can be adjusted vertically or horizontally towardor'away from either riffle'and toward or away. fromthe deck,

said flange serving to separate the deck space into front and rear planes, communication between the front and rear planes being had under the flange, and means for vibrating the deck to cause wave movements of the water in the front and rear planes.

2. In a separator of the class described, the combination'with a deck having front and rear riffles, of end plates fixed to the deck and abutting the ends of the riflles, an inclined apron adjustably connected with the endplates and having a vertical depending flange adapted to-bepositioned between theriflies and spaced from the deck, said flange serving to separate the deck space into front and rear planes, communication between the front and rear planes being had underthe flange, each 'rifile having a 'discharge apron associated therewith, and

means forvibrating the: deckto cause wave movement of the water in the front and rear planes, as and for the purpose set forth. 3. In a separator of the class described, the combination with a deck having front andrear riflles, of end plates fixed to the deck and abutting theends of the riifles,
